Hillary's filly

From NBC's Christina JamisonJust days ago, Sen. Hillary Clinton asked volunteers in Louisville, KY to "bet on the filly" in the Kentucky Derby. At a later event in Indiana that day, Clinton told the audience that she asked Chelsea, who attended the derby, to put a bit of money on Eight Belles, the only filly in the race.

Sadly -- after finishing second in the Kentucky Derby yesterday -- Eight Belles broke her front ankles in the race and was euthanized shortly thereafter.

It was an unfortunate metaphor for the senator trying to stage a comeback in the Democratic primary. Like the 15-to-1 longshot Eight Belles, Clinton is a longshot herself, behind Obama in the delegate count and NBC's popular vote count.
